Feast on weird facts with What If? and this week’s top iTunes picks

So you don't have to slog through a lake of reviews to find something you’re just going to put down after 10 minutes, Cult of Mac has waded through the iTunes Store to compile a list of the best new books, movies and music to come out this week.
This week we’ve found a new documentary that will change the way you look at the food industry, a book that answers some of life's most important (and ridiculous) questions, and a metal album that's so good, it'll even get your to do some headbanging.Enjoy!
